When a woman is approaching labor, the cervix begins to thin and shorten. (think of a polo neck jumper becoming a crew neck jumper). Before labor, the cervix is around 2 to 3 cm in length. The shortening and thinning is known as effacement. Dilation (opening) of the cervix may occur at the same time - particularly in first time moms.
Your cervix has thinned out 60%
== == Your cervix prepares for birth by softening and thinning, or effacing. You won't feel this sign of labor happening. Instead, your health care provider will check for signs of cervical change with vaginal exams. Effacement is often expressed in percentages. When you're 50 percent effaced, your cervix is half its original thickness. Your cervix must be 100 percent effaced, or completely thinned out, before a vaginal delivery
it mean that person not in the stage of disease which shows symptoms but he has organisms in body which cause disease. if the number of microorganism is increased 40 percent, it shows symptoms OR, it could apply to the childbirth process. Basically how much the cervical opening has pulled back or thinned. But this is also tied to how much the cervix has dilated, or opened up to allow the child to be born. Fully dilated is 10 cm.
Your cervix must dilate (open up) to 10 centimeters before you can essentially, 'push' the baby out. So half a cm is good progress, though it seems a bit early at 29 weeks? 75% effaced: you have to be 100% effaced (thinned out) for the cervix to fully dilate & ready to deliver the baby. So you're just about finished there.
effacement The thinning and shortening of the cervix. Measured in percentages from 0 - 100%
50% is out of 100% which means your cervix is paper thin. Once your cervix is dialated to 10cm & your 100% effaced baby is ready to be born. How long it could be in this position, depends on your body.
The question here should really be when CAN you feel your cervix

If your cervix is closed in the front but open in the back, this might mean you are about to start your period. It could also mean that you are ovulating.
